获取UITableViewCell中UITextField的值方法总结

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

    NSInteger row = [indexPath row];

     

    static NSString  *CellIdentifier = @"CellIdentifier";

     

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

     

    if (cell == nil) {

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

        cell.selectionStyle = UITableViewCellSelectionStyleNone;

    }

     

    cell.textLabel.text = [_passwordArray objectAtIndex:row];

     

    CGRect textFieldRect = CGRectMake(0.0, 0.0f, 215.0f, 31.0f);

    UITextField *theTextField = [[UITextField alloc] initWithFrame:textFieldRect];

    theTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;

    theTextField.returnKeyType = UIReturnKeyDone;

    theTextField.secureTextEntry = YES;

    theTextField.clearButtonMode = YES;

    theTextField.tag = row;

    theTextField.delegate = self;

 

//此方法为关键方法

    [theTextField addTarget:self action:@selector(textFieldWithText:) forControlEvents:UIControlEventEditingChanged];

     

    switch (row) {

        case 0:

            theTextField.placeholder = @"请输入旧密码";

            break;

        case 1:

            theTextField.placeholder = @"请输入新密码";

            break;

        case 2:

            theTextField.placeholder = @"请再次输入新密码";

            break;

        default:

            break;

    }

     

    cell.accessoryView = theTextField;  

    [theTextField release];

     

    return cell;

}
